UAE-based Masdar Institute of Science and Technology has filed a provisional patent application with the US Patents and Trademarks Office for a new solid polymer electrolyte technology for Li-ion batteries.
This is the first lithium battery-related patent application filed by Masdar Institute.
A team of scientists and researchers led by Dr. Raed Hashaikeh, Associate Professor, Materials Science and Engineering, Masdar Institute, successfully developed the first operational 2032-coin cell type lithium battery using the new technology, termed “solid polymer electrolyte containing networked cellulose/PEG/LiClO4”. The team included Materials Science and Engineering students Yarjan Abdul Samad, Ali Asghar, and post-doctoral fellow Dr. Boor Lalia.
The electrolyte material can be used to make batteries of varying sizes for different applications. It also has an enhanced room temperature ionic conductivity and enhanced mechanical stability which enables it to be used at a wide temperature range. This can be achieved without adding any flammable organic solvents that are typically used with lithium-ion batteries. In addition, conventional solid polymer electrolytes have poor mechanical properties at elevated temperatures, compared to the electrolyte developed at Masdar Institute.
The new technology may not have any direct relation with the Mitsubishi EVs that are being piloted at Masdar Institute. However, EVs in general that use Li-ion batteries—especially in extreme weather conditions and desert regions including the UAE—can therefore benefit from the functional and mechanical stability of the newly developed electrolyte at elevated temperatures.—Dr. Raed Hashaikeh
Masdar Institute was established as an on-going collaboration with the Massachusetts Institute of Technology (MIT).
